i tried to create a dedicated server using this tutorial http://maniaplanet.github.io/documentat ... basic.html and the files mentioned on a pc with ubuntu. I followed this and others tutorials and the server went online on TMStadium but i can't enter it. It's the first time i try to create one and i'm still a bit newbie.
It says "Could not contact with server", but the server remains online.
I tried following the specified ports but it didn't did anything. I tried many solutions i saw online but nothing else helped

Any suggestions?
Thank you in advance
